Vintage Window Energy Solution!

Introducing, Slim Line Insulating Panes or SLIP

The SLIP (Slim Line Insulating Pane) is an innovative and cost-effective way to retain your original vintage glass windows, while making them more efficient and saving you money. SLIPs are designed to update single-pane wood windows to modern standards. We have made it possible to add an additional pane directly to each sash, without removing or altering their original windows. This simple solution can help out Single hung, double hung, casements, picture windows and more. When SLIPs are added to operating windows the sash are kerfed and weatherstripped and fitted with a hidden balance system which results in a smooth operating window that you dont have to fight with

A SLIP can will dramatically boost insulation power in your windows. Which will bring great savings in your month to month energy bills.  In terms of insulation power, they are neck and neck with insulated glass conversions.

SLIPs are highly effective, well designed and well-priced, giving you superior value when compared to alternatives. Storm windows can be big bulky and a hassle. SLIPs have a sleek look and feel with a low profile that blend into the sash; you’ll hardly know they are there. Another key aspect is that SLIPs will ensure your window sash remains fully operable, without the need to open two sets of windows as you sometimes get with storm windows. you’ll retain FULL functionality without having to alter your vintage glass.

Some of the benefits of the SLIP:

  • Increased energy efficiency

  • Maintains original beauty and charm of existing windows
  • Windows can stay historically accurate and functional
  • Solid, well-designed construction and material
